DEVICE FOR CUTTING FABRIC BLANKS FROM WHICH TO MAKE COLLARS. &c.

SPECIFICATION formingpart of Letters Patent No. 269,312, dated December 19, 1 8 2.

Application filed July 5, 1882.

(No model.)

To all whom it may concern Be it known that l, GEORGE E. NORRIS, of the city of Troy, county of Bensselaer, and State of New York, have invented a new and useful ImprovementinDevicestorOuttingFabric Blank Forms from which to Make Collars, Cuffs, &c., of which the following is a specification.

My invention relates to a manner of constructing devices for cutting blank forms from which to make collars, cuffs, and other similar articles.

My invention consists, as will hereinafter be more fully described, in the combination, with a die having a cutting-edge, of an interior piston-plate, the exterior edge of which is coincident to and in sliding contact with the cuttingedge of the die, a cross-bar or a series of crossbars oppositely attached to the interior sides of the die, at its top or near its top, and each of them sleeved to receive a piston'rod constructed at its upper end to slide in the crossbar sleeve, and its lower end attached to the piston with a spring, encircling each rod between the crossbar and the piston-plate.

In the accompanying drawings, forming a part of this specification, there are two figures illustrating my invention, and in both of which the same designation of parts by letter-reference is used.

Figure 1 shows in perspective a device for cutting blank forms from fabric, and which device contains my invention. Fig. 2 shows a verticalsection of the samedevice, and as taken on the line 00 m of Fig. l.

The several parts constituting my invention are designated by letters of reference, and de scribed asi'ollows:

The letter K indicates a die constructed to cut a rectangular form of greater length than width.

D D D indicate three cross-bars, which are shown at S as, secured to the interior sides of the die at their top, and theletterA in each of these crossbars indicates an opening formed in said bars, which is sleeved downwardly, as indicated at D in Fig. 2.

The letter B indicates a piston-plate arranged within the die, and P designates the lower cutting-edge of the latter, with the cutting-edge of the die and the exterior edge of the piston in sliding contact.

The letter M designates a piston -rod attached to the top of the piston-plate B at S the upper end of the rod M being-constructed with the guide-plate S the latter being free to move up and down in the sleeved opening A, formed in the cross-bar D. Between the under side of latter and the top of the piston B, as shown, is placed the spring S, constructed so as to surround the piston-rod.

Within the die shownherein there are three cross-bars, as indicated at D D D, and each of which contains the same mechanism that is shown in the section, Fig. 2, but with the exception that all connect with one and the same piston B.

When the die thus constructed under press- 7 ure is employed to cut its forin in a superimposed series of fabric thicknesses the piston, being atthe commencement below the cuttingedge of the die, commences to press and condition the several layers of material with compaetness before the knife-edge of the descending die commences to cut, and when the latter passes the piston-edge and does commence to cut the cutting-edge of the die and the exterior edge of the piston will form a shear engagement or sliding contact which starts the cutting evenly, and, in connection with the pressure, will hold the laid thicknesses firmly and so as to prevent their crawling away from the descending knifeedge of the die. When the die is raised and the pressure removed, then the spring forces out the piston, and with it the cut blanks.

In the construction of dies for cutting fabric blanks according to my method one or more sleeved cross-bars may be arranged within the die, provided they have the same construction of spring and piston-rod connected with the piston, and while I have shown and described a helical spring as encircling the piston-rod to increase the pressure of the piston on the fabric as it descends, a rubber spring encircling the rod may be used in place of the helical spring, if desired, to produce the same result.

I do not limit my invention to any particular form of die, further than that it shall be of such a form as shall be adapted to employ a piston-plate actuated and arranged to he operated by the same factors and in the same manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a die for cutting blank forms from a series of superimposed thicknesses of fabric, the combination of a die having an open interior and a cutting-edge, a piston-plate within the die, the exterior edge of which plate forms a sliding engagement with the cutting-edge of the die, a sleeved cross-bar secured to the interior of thedie, at or near its top,a piston-roll at its lower end attached to the piston, with its upper end constructed to slide in the sleeved cross-bar, and a spring arranged between said cross-bar and the top .of the piston, substantially as and for the purposes herein set forth.

2. In a die for cutting blank forms from a series of superimposed thicknesses of fabric, the combination of a die having a hollow interior and a cutting-edge, a piston-plate within the die, the exterior edge of which piston-plate is in sliding contact with the cutting-edge of the die, a series of sleeved cross-bars arranged Within the die and secured to its interior, at or near the top, a piston-rod attached to the piston at one end and construct-ed to slide in each of the sleeved cross-bars, and a spring arranged between the piston and each of the cross-bars, as and for the purposes herein described and set forth.

Signed at Troy, New York, this 16th day of June, 1882.

GEO. E. NORRIS.
